基于 [主题：xxx] 自动生成一张高审美的“剪影宇宙 / 收藏版叙事海报”。不要默认使用瓶子、沙漏、玻璃罩、怀表这类常见容器，而是让 AI 自行选择最具象征性、视觉张力最强、最适合该主题叙事的外轮廓。这个剪影可以是器物、建筑、大门、高塔、拱门、穹顶、楼梯间、走廊、雕像、侧脸、眼睛、手、头骨、翅膀、面具、镜子、王座、戒指、裂缝、光幕、影子、几何形体、空间剖面、舞台框架、抽象符号，或任何更有创意、最能代表主题的轮廓。
目标不是简单地把一个世界塞进某个物体，而是让整个主题宇宙自然地在这个轮廓内部、边缘与穿透关系中生长出来。轮廓必须优雅、可识别，并在构图中占据主导位置。在轮廓内部或边界附近，生成一个与主题紧密相关、层次丰富的叙事世界，包含标志性场景、关键建筑或空间、象征与隐喻、角色或文明痕迹、前中后景层次，以及带有情绪张力的氛围。门、楼梯、桥、水、烟雾、道路、光源、废墟、机械结构、风景、抽象形态、生物、道具等元素都应统一并自然融合，而不是拼贴堆砌。
最终画面应具有高端收藏海报的设计感。大形要稳，主轮廓必须一眼可辨，内部世界要有深度、结构和呼吸感。细节丰富但不过度拥挤。可以加入小型人物剪影、远景建筑、光束、门洞、桥梁、台阶、走廊、倒影、天窗或远景结构，用于增强尺度感、故事感和史诗氛围。整体气质应安静、宏大、精致、余韵悠长，而不是喧闹或堆满信息。
融合收藏版电影海报、高端叙事视觉设计、梦幻水彩肌理与精致纸张印刷感。强调纸张颗粒、羽化边缘、水彩笔触、柔和扩散、空气透视、轻雾、选择性体积光、光线穿过雾气、充足留白和克制版式。画面应具有高级、诗意、庄严、神圣、怀旧、安静和神话感。
让 AI 根据主题自行选择高阶配色，但要保持统一、克制、有品位、低饱和、高级。避免混乱高饱和、廉价霓虹或塑料数码色。合适的配色家族可以是黑金灰、冷蓝灰、雾白灰、棕红配米白、深铜色、旧纸色、深海蓝、暮色紫或银灰，只要服务于主题即可。
最终要求：第一眼就能感受到强烈主题识别与记忆点鲜明的轮廓；第二眼能读出完整叙事世界；第三眼近看仍然有细节和余味。避免通用背景、硬拼贴构图、模板化奇幻素材、电子游戏宣传图气质、过度卡通化，或因为过度写实而破坏艺术氛围。如果合适，可以加入低调的标题、编号、签名或标记作为海报设计的一部分，但绝不能压过主体画面。
Prompt · English
Based on [topic: xxx], generate a high-craft "silhouette universe / collector's edition narrative poster". Avoid defaulting to common containers like bottles, hourglasses, glass cloches, or pocket watches — instead let the AI choose the most symbolic, visually charged silhouette that best fits the topic's narrative. The silhouette can be an artifact, building, gate, tower, archway, dome, stairwell, corridor, statue, profile, eye, hand, skull, wing, mask, mirror, throne, ring, crack, light curtain, shadow, geometric form, spatial cross-section, stage frame, abstract symbol — or anything more creative that best embodies the topic.
The goal is not to cram a world into an object, but to let the entire thematic universe grow naturally inside, along, and through the contour. The silhouette must be elegant, recognizable, and dominant in the composition. Inside or near its boundary, generate a richly layered narrative world tightly tied to the topic — signature scenes, key buildings or spaces, symbols and metaphors, characters or traces of civilization, foreground/midground/background layering, and an emotionally charged atmosphere. Doors, stairs, bridges, water, smoke, roads, light sources, ruins, mechanical structures, landscapes, abstract forms, creatures, and props should all integrate cohesively rather than as collage.
The final image should feel like a high-end collectible poster. Major shapes must read clearly; the primary silhouette must be unmistakable; the inner world should have depth, structure, and breathing room. Detail should be rich but not crowded. Add small character silhouettes, distant buildings, light beams, doorways, bridges, steps, corridors, reflections, skylights, or distant structures to amplify scale, story, and epic atmosphere. The mood should be quiet, grand, refined, and resonant — never noisy or information-dense.
Blend the feel of collector's edition movie posters, high-end narrative visual design, dreamy watercolor textures, and refined paper-print quality. Emphasize paper grain, feathered edges, watercolor strokes, soft diffusion, atmospheric perspective, light mist, selective volumetric light, light cutting through fog, generous whitespace, and restrained typography. The image should feel premium, poetic, solemn, sacred, nostalgic, quiet, and mythic.
Let the AI pick high-end colors that fit the topic — but keep them unified, restrained, tasteful, low-saturation, and refined. Avoid chaotic high-saturation, cheap neon, or plastic digital colors. Suitable palettes include black/gold/gray, cool blue-gray, misty white-gray, brown-red on cream, deep copper, old paper, deep sea blue, twilight purple, or silver gray — whatever serves the topic.
Final criteria: a strong, memorable thematic silhouette at first glance; a complete narrative world readable on second look; surviving detail and aftertaste on close inspection. Avoid generic backgrounds, hard-collage compositions, templated fantasy stock, video-game promo vibes, over-cartooning, or photorealism that breaks the artistic mood. If appropriate, include subtle titles, edition numbers, signatures, or marks as part of the poster design — never overpowering the main image.
